Specification of Letters Patent.

Patented Mar.`11, 1913.

Application led Aprill 4, 1912. Serial No. 688,540.

To all whom t mag/lconcem:

Be it known that I, HAROLD S. CASE, a citizen of the United States, residing at Standfordville, -in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Heaters or Muffler Attachments; and I do hereby declare the following to be a full,V clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to heaters, and it more particularly. relates to a combined foot warmer and mufller, designed'to be attached to the foot rail -of an automobile pr the like and to be heated by the exhaust from the engine thereof'.

An object of 'the invention is to provide a device of this character, with appliances and accessories whereby 'it may be att-ached to either a cylindrical or non-cylindrical foot rail.

A further object of the invent-ion is to provide a device of this character which absorbs heat from the engine exhaust and transmits the heat, by conduction, to the top surface of the foot warmer.

A still further object is to provide a device of this character, of su'ch simple construction as to render it comparatively inexpensive and ,easily cleaned, when necessary,

and withal, thoroughly efficient in operation.

Other object-s and advantages may be recited hereinafter and in the claim.

In the accompanying drawings which form a part of this application, Figure 1 is a horizontal sectional view along the line 1 1 of Fig. 2.' Fig. 2 -is a vertical sectional view along the line 2 2 of Fig. 1. Figs?, is a transverse vertical sectional View on the line 3 3 of Fig. 1, and, Fig. 4 is a perspective view showing the top of the heater inverted.

Referring to the drawings, in which similar reference characters designate corresponding parts throughout thel several views, the body 5 of the heater consists of an' elongated rectangular boX, whichfmay be made of cast iron or of any proper material. The bottom and sides of the box 5 are preferably lined with thick' sheets of asbestos 6 and with an inner lining 7 ofsuitable non-corrosive metal having slight heat conducting properties. This box is provided with a cover 8, having a series of depending parallel flanges 9 formed integrally therewith, said flanges being arranged in staggered relation; that is, each 'alternate flange extends nearer to one edge of the cover than the other flanges, while said other flanges extend nearer to the opposite edge ofthe cover than the first said flanges. It will be-seen," therefore, that Vwhen the cover is fitted onto the box, certain of the flanges fit closely against the inner lining 7 of one side and are spaced'apart, as at 10, from' the opposite side wall, while the alternate flanges are spaced apart from the first said side wall, as shown in Fig. 1 and by the dotted line in Fig. 3. Each endof the box 5 is apertured at 11 for the reception of pipe connections 12, adapted to be connected with the exhaust pipe of an engine.

By referring to'Fig. 1, it will be seen that the flanges 9 constitute a series of partit-ions in the box 5` said partitions forming a series ofchambers 13 which are connected by as. sages 14. I t is also seen that the' partitions' chambers, will pass out through the other pipe connection 12. It will be seen that the exhaust is considerably retarded in its tort-uous passage through the fheater, also that but little, if any, of the exhaust escapes from the heater without having first come int/o direct contactV with one of the partitions or flanges 9 and imparted its heat to said partitions. T he exhaust also comes into contact with the portions of the cover 8 between the partitions, and with the -side and bottom `linings, 7 but, the latter having slightv heat conducting propertles, absorbs but little of Athe heat, so that the top and -its flanges absorb the major portion of the heat fro-m the exhaust. vAs the heat is given outA from .the top cover 8, more heat is `conducted thereto by the flanges .9,v the enlarged or diverging junctions ofthe flangeswlth the cover serving to more Ithoroughly distribute the heat throughout the top ofthe cover.l

The cover 8 may be securedon the box by any proper means, but preferably'by means rendering the cover easily removable.

In order to regulate the'degree of heat imparted to the feet of the user, I provide a losA carpet 15, secured to the cover 8, at its or-v ward edge, its rear edge being free to fall loosely against the rear side of the box, so that when the Weather is moderate, said carpet protects the users feet from an undesirable degree of heat; while, lwhen the Weather is excessively cold, the carpet may be raised, as shown in broken lines, Fig. 3, and the shoes of the user come into direct contact with the top of the cover 8, while the carpet acts as a covering for` said shoes an'd thereby protecting the wearers feet from cold drafts, in an obvious manner.

In Fig. 3, this improved heater is shown attached to a cylindrical foot rod 16, by means of a clamping device which consists of a curved bracket 17, apertured at 18 for the reception of the thumb screw 19, arcuate clamping jaws 2O coactwith the bracket 17 and the screw 19 for securing the heater to the foot rod. It is seen that the lower edges of the upper member 2O and the upper edges of the lower member 20 are on horizontal and parallel planes, and are therefore adapted to'receive a at foot rail therebetween, instead of the round foot rail 1G. It is also obvious, that I may substitute other clamping jaws than the jaws 20, in connection with the bracket 17, for att-aching the heater to the foot rails of different shams and sizes.

It is seen that I have provided a device which is fully capable of attaining the forcgoing objects and in a thoroughly` practical and eliicient manner.

I do not limit my invention to the exact details yof construction, combination and arrangement of parts, as described and illus trated, but my invention may only be limited by a reasonable interpretation of the following claim.

What I claim is:

A heater and muffler attachment coniprising a box having an inlet and an outlet at opposite ends thereof, and adapted to havel HAROLD CASE.
